0-5 filters, need help
Hi, I just recently had access to a dark room while on a trip to new york and hadn't used a darkroom in 7 years. When i got home i realized that i really needed a dark room and built one up. now that i have a darkroom that i can use at my leisure i have been wanting to use filters. im not very knowledgeable when it comes to filters and need some help with them. I cant seem to find good write up or explanation online for standard filter usage, im only finding split filter usage. if anyone has suggestions or a link to a good article on using filters thank would be great.
